SPECIFICATION forming part of Letters Patent No. 733,482, dated July 14,19 03.

Application filed November 6, 1902. Serial No. 130,323. (No model.)

To all whom it may concern.-

Be it known that I, MARIA HOLMAN, a citizen of the United States,residing at Waukomis, in the county of Garfield and Territory ofOklahoma, have invented a new and useful Mechanical Movement, of whichthe following is a specification.

My invention relates to mechanical movements, and has for its object toprovide a comparatively simple and inexpensive mechanism which will beefficient in operation and one in which a continuous rotary motion maybe imparted to a driven wheel or shaft from a driving band or belt whichoperates with a reciprocatory motion.

To these ends the invention comprises in a mechanical movement thecombination with a driven wheel, of a shaft operated thereby, adrivingbelt having its flights arranged above and below the driven wheelin operative connection therewith, means for reciprocating thedriving-belt, and means adapted to move the flights of the beltalternately out of operative connection with the driven wheel.

The invention further comprises the details of construction andcombination of parts more fully hereinafter described.

In the accompanying drawings, Figure 1 is a perspective view showing myimproved mechanism applied for driving a clotheswringer. Fig. 2 is anenlarged sectional elevation illustrating the mechanism for actuatingthe wringer-rolls. Fig. 3 is a sectional plan view illustrating theoscillatory drivingwheel. Figs. 4: and 5 are detailed sectionalelevations illustrating the manner of mounting the main bracket.

Referring to the drawings, 1 indicates a suitable framework, havingmounted thereon the framework 2, which carries the wringerrolls 3 andat.These parts may be of any suitable or desired construction, inasmuch asthey are entirely foreign to my invention and are merely employed hereinto illustrate one of the various devices to which the present inventionmay be applied; 7

5 indicates a gear-wheel fixed on the shaft of the upper wringer-rolland adapted to intermesh with a similar gear 6, mounted on the shaft ofthe lower wringer-roll l and by which the Wringer-rolls are adapted tobe driven in unison one from the other.

7 indicates a sprocket-pinion fixed on the shaft of the upperwringer-roll, and S a similar pinion fixed on the shaft of the lowerwringer-roll. These sprocket-pinions may be formed integral with theirrespective gears 5 and 6 or they may be entirely independent thereof, aswill be readily understood.

9 indicates a bracket, preferablysecured to thewringer-frame andprojecting horizontally therefrom in the form of two arms disposedvertically one above the other with their outer ends converging to ameeting-point, as clearly shown in Fig. 2.

10 is a guide-wheel, preferably provided with sprocket-teeth and mountedfor rotation on a horizontal stud or the like 11, carried at the outerend of the bracket 9.

12 indicates a pulley or wheel mounted in' suitable bearings in avertical bracket 13, which'is provided, preferably, with a hori- Zontalbase 14., adapted for attachment in the manner hereinafter'described tothe framework 1. The pulley or wheel 12 is provided with suitablesprocket-teeth and with an operating handle or lever 15, which inpractice may be moved vertically up and down to impart a reciprocatorymotion to the pulley and to a chain or belt 16 driven thereby. This bandor belt is preferably in the form of a sprocket-chain, which extendsfrom the driving-pulley 12 to the guide-pulley 10, with its upper flightarranged above the sprocket-pinion 7 and its lower flight beneath thesprocketpinion 8. The flights of the chain are adapted to alternatelyengage and drive their re,- spective pinions in the manner and for thepurpose hereinafter described. The upper flight of the chain 16 overliesa guide 17, preferably in the form of a small sprocket-pinion journaledin the bracket 13, and the lower flight of the chain underlies a similarguide 18, also journaled in the bracket. I

19 indicates a normally expanded spring vertically disposed and havingits. ends mounted in sockets 20, formed in the shanks 21 of suitableshoes 22, slidingly mounted in the arms of the bracket 9 and providedwith suitable heads, which present smooth outer surfaces to and bearagainst the respective upper and lower flights of the chain 16 for thepurpose to be presently described.

The base 14 of bracket 13 is preferably in the form of a round metaldisk and is centrally pivoted to the framework 1 by means of apivoting-bolt 23 and is further held in place by means of thumb-screws24, by the removal of which latter the bracket may be swung around onits central pivot to the position indicated in dotted lines in Fig. 3when desired.

In the operation of the device, supposing the parts to be in theposition illustrated in Fig. 1, the operator moves the handle 15 of thedrive wheel downward, which action causes the upper flight of chain 16to tighten, thus compressing the spring 19 and permitting the saidflight of the chain to engage the sprocket-pinion '7 to impart motion tothe upper wringer-roll 3, the motion from which latter is transmitted,through the medium of the intermeshing gears 5 and 6, to the lowerwringer-roll 4. When the handle 15 is moved upward, it will rotate thedrive-wheel12 in the opposite direction, tighten the lower flight of thechain, cause the same to compress spring 19 in the opposite direction,and permit the said lower flight of the chain to engage sprocket-pinion8 and continue the movement of the lower wringer-roll 4 and through themedium of the intermeshing gears the motion of the upper wringer-roll.Thus it' will be seen that by reciprocating the handle 15 areciprocatory motion is imparted to the drive-wheel 12 and to the chain16 and that this reciprocatory motion, owing to the upper and lowerflights of the chain alternately engaging the pinions 7 and 8, imparts arotary motion in one direction to the wringer-rolls. It is to be notedthat the spring 19, being normally expanded, tends to force the flightsof the chain out of engagement with the pinions. Consequently when oneof the flights is tightened through theaction of the drivewheel it willcompress the spring sufficiently for the chain to engage its pinion, andthe other flight becoming slack by the same operation will be moved bythe spring out of engagement with its pinion. Thus the spring willalternately move the respective flights of the chain out of engagementwith the pinions 7 and 8.

From the foregoing description it will be seen that I produce amechanism which is simple of construction and may be readily applied toany apparatus where it is desirable to impart a rotary motion to asingle or plurality of driven shafts from a driving-wheel which has areciprocatory motion, and in attaining this end I do not limit orconfine myself to the precise details herein shown and described,inasmuch as various changes therein, such as would suggest themselves tothe skilled mechanic, may be made without departing from the spirit orscope of my invention.

Having thus described my invention, what I claim is- 1. In a mechanicalmovement, the combination with a driven wheel, of a shaft operatedthereby, a driving-belt having its flights arranged above and below thedriven wheel in operative connection therewith, means for reciprocatingthe driving-belt, and means adapted to move the flights of the beltalternately out of operative connection with the driven wheel.

2. In a mechanical movement, the combination with a pair of drivenshafts of intermeshing gears connecting the shafts, a driving-belthaving its flights arranged respectively above and below the gear-wheelsin operative connection therewith, means for reciprocating thedriving-belt, and means adapted to move the flights alternately out ofoperative connection with the gear-wheels.

3.

5. In a mechanical movement, the combination with a pair of drivenshafts of inter meshing gears connecting the shafts, a driving-belthaving its flights arranged respectively above and below the gear-wheelsin operative connection therewith and adapted to alternately drive thesame, means for recip-- rocating the driving-belt, a spring interposedbetween the flights of the driving-belt, shoes engaging and actuated bythe spring, to antomat-ically move the respective flights alternatelyout of operative connection with the gear-wheels, and means for guidingthe shoes.

6. In a mechanical movement, the combination with a pair of drivenshafts of intermeshing gears connecting the shafts, a drivewheel adaptedto be oscillated, a driving-belt operated by the wheel and having itsflights arranged respectively above and below the gear-wheels andadapted to alternately drive the same, and means adapted to move theflights alternately out of operative connection with the gear-wheels.

In a mechanical movement, the combination with a pair of drivenshafts, of gearing connecting the shafts, sprocket-gears conflightsarranged respectively at opposite sides of the sprocket-wheels inengagement therewith, an oscillatory operating device for driving thechain, and means for moving the flights of the chain alternately out ofengagement with their respective sprockets.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses. v
